SHOCK-ABSORBER.

' Application filed May 31, 1919. Serial No.

To all whom it may concern:

Be it known that I, Loom H. OBERREIOH, citizen of the United States, residing at Indianapolis, in the cou ty of Marion and State of Indianafhav'e' invented a new and useful Shock-Absorber, of which the following is a specification.

It is the object of my invention to pro vide a simple form of shock absorber, which can be applied to Ford cars without requiring any material change in the spring an axle structure thereof but is simply substituted for the ordinary supporting shackle.

d, and which is particularly at the spring en the rebound shocks.

ada ted to take T e accompanying my invention. igure elevation of a with a shock absorber 2 is asimilar view of equipped with such a shock absorber; 'an Figs. 3 and 4 are perspective views of parts for the rear axle. to the front-axle structure 10 and the Ford conhas the standard 1 is a fragmentary of my invention; mg. a rear axle and spring Referring first shown in Fig. 1, the main spring struction, and the axle perch 1 2 fromfwhich the end of the spring 10 is supported. The perch 12 projects upward and inward from the axle. The end of the spring 10 and the end of the perch are both provided with eyes. None of this need -be at all changed from standard. In the standard construction, however, the eyes of the perch and the main spring are con-. mated by a shackle or link. I remove that shackle or link, and in place of it provide-a lever 13. which has a link portion 14 substantially corresponding to the standardshackle or link and pivotally connected to both such eyes. Thus by reason of this portion 14 of the lever 13, the spring 10 15 Sue ended from the perch tial y the same way as in the standard construction. In add1tion,.the lever 13 projecting arm, which at its end is provided with a cup"15 in which isseatedthe upper end of a compression spring-16, the lower end of which bears against a spring seat 17 suitably mounted on the axle 11 between theperch 12 and the end of the axle. The s ring 16 is preferably adjustable, as by 3 within the cup 15 an 31S adjusta e by a screw 19. v

such spring,

12 r in substanhas a 3 rection to ate 18 whichbears a ainst its upper en it spreads as in the standard and turns the lever 13 in the the spring pushed down,

direction to relieve ,the pressure on 16. On the rebound, however, the lever 13 must turn in the opposite direction, and this movement is opposed by thespring 16, which thus takes the rebound and reduces its effect on-the car body.

The rear-axle structure is in principle the same as the front-axle structure. rear spring 20, the rear axle 21, and the rear perch 22 are standard. In place of the ordinary shackle .connecting eyes at the endof the spring 20 and the perch 22, I provide a lever 23, (shown in detail in Fig. has a portion 24 which corresponds in function to thestandard shackle or link; and this lever 23 has a projecting arm for coil erating with a rebound-taking. spring 26. ever, as the perch 22 springs from the en- (1 largement provided for the brake structure the rear axle 21, it is imposthat its upper Therefore, in abutment for erch 22 a sadig. 3,) which at the end of sible to locate the spring 26 so order to provide a suitable I mount on the die 27, (shown in detail in bears against to the perch eye by the pivot bolt 28 by which the lever 23 is attached to such eye.

29 which abuts of the spring 26 to prevent displacement of the spring. The projecting arm of the lever 23 and the fin er 29 of the saddle 27 are located above t eperch 22, in order to clear the other parts, and such projecting arm projects partly overthe .main' spring 20; ut this is merely for the purpose of noninterference with other parts.

In operation, the rear-axle shock absorber is substantially identical with the front-axle shock absorber. When the spring 20 is depressed,'the lever 23 is turned in the direlieve the compression of the spring '26.- Upon reboun however, the lever 23 is turned in the opposite direction; and thisturning is resisted by the spring 26, which thus takes the rebound.

.In both forms of the-shock absorber, the main body spring may be de ressed without interference from the s Patented Dec.7,1920.

Here the the outer face of the perch between 1ts eye and its base and is attached ock-absorber 4,) which 26, so that finger 23, both of which are'shown as having bosses 30 projecting into the ends spring; but upon rebound the shock-ab sorber spring resists the movement of the lever connecting the two springs, and so lessens the effect of the rebound on the vehicle body.

I claim as my invention:

1. In combination with the main spring, axle, and perch of an automobile; a lever having a link portion directly pivotally connected to the perch and to the main spring, and a projecting arm portion; and a spring acting on the projecting arm portion of said lever in the direction to oppose the turning thereof which is produced by the separation of the main spring and axle upon rebound, said lever being free from spring opposition in its turningin the opposite direction.

2. In combination with the main spring, axle, and perch of an automobile; a lever having a link portion directly ivotally connected to the perch and to t e main spring, and a projecting arm portion; and a spring acting between said projecting arm portion of said lever and the axle in the direction to resiliently oppose the turning of said lever which occurs when the spring and axle separate upon rebound.

3. In combination with the main spring, axle, and perch of an automobile; a lever having a link portion directly pivotally connected to the perch and to the main spring, and a projecting arm portion; and a compression spring acting between said projecting arm portion of said lever and the axle in the direction to resiliently oppose the turning of said lever which occurs when the s ring and axle separate upon rebound.

4. n combination with the body spring,

axle, and a perch carried by the axle and projecting upward and inward therefrom, a link projecting downward and inward from the free end of the perch and connecting said free end to the end of said body spring, said link having a projecting arm, and a spring acting between said arm and the axle and opposing the movement of the link which occurs when separate upon rebound.

5. In combination with the main spring, axle, and perch of an automobile, a lever havin a link portion directl pivotally connecte to the perch and to t e main spring and a projecting arm portion, and a separate spring acting on the rojecting arm portion of said lever inthe direction to oppose the turning thereof whi h. is produced by the se aration of the main spring and axle upon the spring and axle re ound.

6. In combination with the main spring, axle, and perch of an automobile, a link directly connecting the end of the main s ring and the end of the perch and by whic the main sprin is suspended from the perch, and a supp ementa spring acting on said link only in opposition to the movement thereof which occurs when the main spring and axle separate upon rebound.
